WCAG Details
What It Is
Web Content Accessibility Guidelines (WCAG) 2.2 is the W3C's technology-agnostic framework for making web content accessible to people with disabilities. Its primary purpose is to define testable requirements across visual, auditory, motor, cognitive, and other needs, using a layered structure of principles, guidelines, and success criteria.
Key Components
- **Four POUR principlesPerceivable, Operable, Understandable, Robust.
- 13 guidelines under POUR with ~90 success criteria at A/AA/AAA levels.
- Normative success criteria plus informative techniques and failures.
- Conformance requires full pages, complete processes, accessibility-supported tech, non-interference.
Why Organizations Use It
- Meets legal benchmarks (ADA, Section 508, EN 301 549, EAA).
- Reduces litigation risk amid rising lawsuits.
- Improves UX, SEO, conversion rates, market reach.

Key Components
- Clauses 4–10: context, leadership, planning (energy review, SEUs, EnPIs, EnBs), support, operation, evaluation, improvement.
- Core elements: energy policy, data collection plan, operational controls, audits, management review.
- Emphasizes demonstrable continual improvement; optional certification per ISO 50003.
Why Organizations Use It
- Drives 4–20% energy/cost savings, GHG reductions, supply resilience.
- Meets regulatory expectations (e.g., EU directives), enhances ESG reporting.
- Builds stakeholder trust, competitive edge in procurement.
Implementation Overview
- Phased: gap analysis, energy review, planning, deployment, audits.
- 12–18 months typical; scalable for SMEs to multinationals; third-party audits optional.
